Accredited mould removal and remediation specialists in London

We specialise in complete mould removal services in London. Our mould specialists provide expert advice and long-term solutions to ensure mould removal. We use advanced techniques and equipment to ensure а mould-free home. Damp and mould problems can lead to respiratory problems, infections, allergies, and asthma, making it crucial to address them promptly.

Reliable mould removal

Our black mould removal service is thorough and efficient. We start with a detailed inspection to identify the extent and type of mould infestation. Using specialised tools, we then contain the affected areas to prevent the spread of mould spores. We also conduct mould testing to ensure accurate identification and effective treatment. Additionally, we focus on mould spore removal by treating the air to reduce the spore count to a safe level.

Comprehensive mould remediation

In addition to mould removal, we offer top-notch mould remediation services. Mould remediation goes beyond just removing the visible mould - it addresses the root cause of mould growth and implements mould prevention strategies to prevent future infestations. Our mould removal experts assess humidity, ventilation, and potential water damage to develop a mould remediation service plan. This plan includes thorough mould treatment to ensure long-term protection.

How we do it - our step-by-step mould treatment process

We create a tailored mould treatment plan based on your home, budget, and specific circumstances. Our Dewpoint-accredited technicians will pinpoint the root cause and resolve mould and mycotoxin issues.

1. Inspection & moisture assessment

We begin with a comprehensive mould inspection of the affected areas to identify the full extent of the problem and its root cause.

During this stage, our mould remediation specialist identifies visible mould growth, assesses contamination severity, and measures moisture levels in walls, ceilings, and surrounding surfaces.

Using specialised hygrometers, our technicians detect hidden moisture conditions that aren't immediately visible - a critical step, as mould thrives in high-humidity environments. Identifying excess moisture allows us to pinpoint what's causing the problem.

By addressing both the contamination and the underlying moisture issues, we significantly reduce the risk of recurrence and ensure a more effective, long-term remediation solution.

2. Air protection & HEPA filtration

Before treatment begins, we install a professional HEPA air scrubber to control airborne contamination and maintain a safe working environment. The system continuously filters the air throughout the process, capturing mould spores, dust, and microscopic particles while preventing them from spreading to other areas of your property. This is essential for protecting indoor air quality during remediation.

The air scrubber operates through a 3-stage filtration system: a pre-filter captures larger particles, a carbon filter reduces odours and vapours, and a true HEPA filter captures 99.97% of particles as small as 0.3 microns, including mould spores.

3. HOCl mould treatment & mycotoxins neutralisation

As part of our mould removal service in London, we apply a professional-grade disinfectant solution - HOCl (Hypochlorous Acid) - to neutralise contamination at its source. Widely used in hospitals and professional remediation services, HOCl is proven for its effectiveness and safety in indoor environments.

This advanced treatment neutralises mould spores and mycotoxins, eliminates bacteria and other microorganisms, and leaves no harmful chemical residues. Non-toxic and environmentally friendly, it is safe for residential properties when applied by trained specialists.

This stage ensures that mould is treated at a microscopic level, not just removed from visible surfaces, making it a critical component of complete mould remediation.

4. ULV dry fog application

Using ULV (Ultra-Low Volume) dry fog technology, we apply the HOCl solution. This method produces ultra-fine particles that disperse evenly throughout the air, allowing the treatment to penetrate areas traditional cleaning methods cannot reach.

The fog penetrates cracks, porous materials, and hidden surfaces while treating the entire airspace of the room, including behind furniture, into corners, and across ceilings. This ensures comprehensive and even coverage throughout the affected area.

By targeting both visible mould and airborne contamination, ULV fogging plays a key role in delivering thorough and effective mould remediation.

5. Physical mould removal (H-class filtration)

After the neutralisation stage, we carry out the physical removal of visible mould using professional remediation equipment with H-Class filtration. This specialist system is designed specifically for hazardous dust and biological contaminants, ensuring mould particles are safely contained throughout the process.

By preventing spores from being released into the air, we maintain a controlled environment during removal. This stage completes the physical aspect of our professional mould removal service, ensuring contamination is safely and effectively eliminated.

6. Final air cleaning & indoor air purification
The HEPA air scrubber continues to operate during and after the mould treatment to filter out any remaining airborne particles. This ongoing filtration captures residual mould spores, reduces contamination levels, and restores cleaner, healthier indoor air within the treated space.

Our mould removal service effectively treats visible contamination and significantly reduces airborne mould spores. However, any mould hidden within walls, insulation, or other concealed spaces may require further investigation as part of a comprehensive mould remediation approach.

Frequently asked questions about mould removal

How much does it cost to remove mould in London?
For a whole house, mould removal costs in London can range from £200 to £3,000 or more, depending on the extent of the problem. It depends on how badly the mould is, what treatment is needed, and if you hire a professional or do it yourself. 
Is professional mold removal worth it?
Yes, professional mould removal is often worth it, especially for large, persistent, or hidden infestations. Professionals can safely remove mould, address the underlying moisture problem, and prevent it from returning.
Do you treat the mould spores in the air?
Yes, our technicians treat both visible mould and airborne mould spores on your property. Airborne mould particles are particularly challenging to detect because they are not visible to the human eye, which is why we use specialist technology to identify mould problems and eliminate them.
Is the chemical you use harmful?
No, the chemicals used in our two-stage treatment are EPA-registered and completely non-toxic.
Will I have to vacate the entire property?
Yes, we may ask you to vacate the property while we carry out the mould treatment and remediation service. This is because the mould spores being targeted can pose health risks to those not wearing the proper personal protective equipment (PPE).
How can I prevent black mould growth in my home or workplace?
To prevent mould growth, it’s important to control moisture levels by ensuring proper ventilation, fixing any serious water leaks and using a dehumidifier in damp areas. Regularly clean surfaces, especially in bathrooms and kitchens, and consider using mould-resistant building materials whenever possible.
Is it safe to remove mould by myself or should I contact a professional?
For small-scale mould problems, you can often use over-the-counter cleaning products or DIY solutions. You can find various mould removal products that are effective for minor issues. However, for larger infestations, significant water damage, or if you’re experiencing health issues, it’s best to hire a professional mould removal company to ensure the problem is thoroughly and safely addressed.
How do I know if I have a mould problem?
There are several indicators that you may have mould in your property. It could be a sign of mould if you experience unexplained allergic reactions such as sneezing, coughing, or a runny nose. Additionally, if you notice that your asthma symptoms are worsening or becoming more frequent, this may indicate mould in your property. Visible mould growth on walls, ceilings, or other surfaces clearly indicates a problem. Finally, persistent dampness or water stains on your property can also signal a mould issue.
